FIELD OF THE INVENTION

This invention relates to an exhausting apparatus for water closet, especially an exhausting apparatus with an air dividing case for water closet.

BACKGROUND OF THE INVENTION

At present, ventilation of toilets, whether public and home, domestic and abroad, is simply to exhaust air direct from toilets with exhaust fans. With this mode of ventilation, air from water closets could still be exhaled into space of the toilet, air in toilet would be with unpleasant odor, and surrounding would be contaminated. Inhaling this type of harmful gas would affect man's health.

There is another design in recent years. In this design, exhaust fan is connected through conduct direct to water closets and exhausts air in water closet. This design may avoid the disadvantage of unpleasant odor in water closet exhaled into the toilet, but it is necessary to provide a set of exhausting Apparatus for each water closet, this would increase investment and have a low utilization rate of exhaust Apparatus. In addition, it is sometimes necessary to install exhaust fans in toilets.

SUMMARY OF THE INVENTION

Purpose of this invention is to overcome shortcoming of prior arts and to provide an exhausting apparatus with an air dividing case for water closet.

The aim of this invention is realized as follows: an exhausting apparatus with an air dividing case for water closet, comprises water closet, exhaust fan and conducts, wherein the air dividing case has an inner chamber with an outlet and inlet. The outlet is connected to the inlet of exhaust fan through a conduct, while the inlet is connected to the water closet through a conduct. An adjustable air valve is equipped between the inlet and the inner chamber, and the outlet of exhaust fan is connected to outdoor through a conduct.

With this Invention, it is possible to provide through holes at the bottom of inner chamber of air dividing case to suck also air in toilets so that to realize vent of air in the toilet. It is possible to provide the through holes with removable lids to facilitate adjustment.

In this invention, it is possible to establish a inlet in inner chamber of air dividing case and to set an air separate plate inside it, which divides the inner chamber into two chambers that does not interlinked each other, namely one chamber to the water closet and other chamber to the toilet.

In this Invention, it is also possible to establish two inlets in the inner chamber of air dividing case, which are located two sides of the air dividing case respectively, so that the Apparatus can be used for two water closets at the same time.

In this invention, it is also possible to establish three inlets in the inner chamber of air dividing case, one of which is located at one side of the air dividing case and other two of which are located at another side of the air dividing case, so that the Apparatus can be used for three water closets at the same time.

In this invention, it is possible to make rear exhaust hole of water closets to be connected through conduct to the inlets of inner chamber, and also to make overflow tube in water tank of water closets to be connected through conduct to the inlets of inner chamber in air dividing case.

Because of aforesaid structure used, this invention can exhaust air with unpleasant odor inside water closets direct to outdoor to prevent harmful gas from inhaled by persons, but also make one set Apparatus possible to be used for multiple water closets and/or toilets, so to reduce cost. It may keep air in toilets brisk and venting even with no exhaust fan installed.
